Judge Patricia Lees told the panel she would accept a majority verdict on the outstanding charge.

The jury was told that Johnson, from Orpington, south east London, set out early in the evening to deliver a phone charger to her friend, Emmanuel Okubote, 20, a convicted crack cocaine dealer and thief, otherwise known as T-Man.

When she arrived at their meeting point in Catford, south London, he jumped into the passenger seat while others climbed into the back of the car, prosecutors said.

Johnson told detectives she was instructed to drive from one place to another late at night and into the early hours of the morning.

When she stopped, her passengers - most of whom she claimed never to have met before - would embark on a looting mission.

She told the court she was ordered to act as his driver and was too frightened to flee.

Asked why she had not refused to drive that night, she told police: "I didn't get the impression they were the sort of people you say no to... I suppose there's a fear of them, there's a general knowledge that these are just not the kind of people who you don't go along with, especially when they are sat in your car and have an idea of your family or registration plate."
